RESOURCES Minister Anthony Roberts has denied NSW Police will afford Metgasco any special protection against protesters sabotaging its mining activities.

Labor MP Adam Searle said the company claimed it was given assurance of police protection as part of ongoing negotiations with the State Government.

"If you are going to send the New South Wales police to run interference for a private company so they can undertake commercial operations then the question is: who should pay for that?" he asked during an estimates hearing.

Mr Roberts said there was "nothing special" about the police arrangements.

"It is just them undertaking their normal duties, that is, to protect in any case where there could be issues of life and property," he said.

"Let me make it very clear that this government believes that the law should be upheld for both owners of property and companies as well as to protect, in some case, protesters.

"Where the police are required they be deployed, again, that is an issue for our very professional NSW Police Force.
